Hey Experts,

I am seeking some help with Javascript.

I have three fields in total.

Field A is linked with Field B and C.

If B is blank, field A should populate with Field C total. If C is Blank Field A should populate with B.

I need to submit my assignment tomorrow. Kindly help.

You may use a custom calculation script for field A  with something like this:

if ( (this.getField("FieldB").value !="") && (this.getField("FieldC").value =="") ) event.value = this.getField("FieldB").value;

else if ( (this.getField("FieldC").value !="") && (this.getField("FieldB").value =="") ) event.value = this.getField("FieldC").value;

else event.value ="";
